The popularity of using projectors for business meetings and in classrooms grows every year. New technologies add ample features and options for both large and portable projectors and projection screens. A typical favorite type of projector is a liquid crystal display, commonly called an LCD projector. With new technology appearing on the market all of the time, LCD projectors do have competitors but still remain at the forefront for use in classrooms and businesses.
Low Cost Projection
A concern for many businesses and schools is the cost of replacement parts and energy use of projector systems. Schools and businesses work on tight budgets, and no matter how useful a piece of technology may be to the implementation of instruction or information, if the upkeep is too expensive the product is often bypassed for a cheaper counterpart. The low cost of running LCD projectors is one reason many businesses and schools choose to use these over other available projectors.
The low cost of manufacturing LCD technology is the reason the costs are low for consumers. Depending on the model purchased, these projectors also have energy saving option modes to help keep the cost of using the projector low. The energy saving modes can also turn off the projector automatically, reduce the amount of light consumption during use, and put the projector in power saving mode.
Bright, Clear Picture Display
Another advantage of LCD projectors is the bright display. The technology of LCD allows for a natural looking image to appear on the screen. While most projections appear on specially made screens, it is possible to use these projectors on white, beige, or gray walls making them ideal for spur of the moment presentations. The images are not grainy and don’t skip, unlike traditional slide or film projectors.
LCD is also popular because it works well in both small and large projection units. The LCD technology translates well to small portable units used in classrooms and business meetings, or large units used in lecture halls. There are certain aspects of LCD projectors that aren’t ideal, but manufacturers consistently figure out new methods of making LCD projection better. Two main concerns are ghost images, where the outline of an image remains even though the image changes, and dead pixels that remain on the screen throughout the duration of the presentation. With advanced technology, these issues should soon become a thing of the past.
